does a candidate-elimination method have to be able to eliminate the
Condorcet winner in a three-candidate scenario in order to be
nonmonotonic with only three candidates?
I'm not quite sure what the intended question is but isn't it enough
to eliminate the candidate with most first preference votes unless it
is the Condorcet winner. This method will be non-monotonic when there
is no Condorcet winner.

More generally, does a candidate-elimination method have to be able
to eliminate the Condorcet winner in a three-candidate scenario in
order to be nonmonotonic with only three candidates?
